7 Claims.

This invention relates to improvements in metal shingles.

One object of the invention is to provide a metal shingle for roofs that may be laid with others in stepped offset rows in simulation of the usual wood shingles.

Another object of the invention is to provide a metal shingle arrangement which is thoroughly weather tight; economical to manufacture; easy to lay by the use of ordinary nails and without any extra clips or the like such as heretofore commonly employed.

Other objects of the invention will more clear- 1y appear from the description and claims hereinafter following.

In the drawing forming a part of this specification, Figure l is a plan view of a portion of a roof showing my shingles applied thereto. Figure 2 is an enlarged, vertical, sectional view corresponding to the line 22 of Figure 1. Figure 3 is a sectional view corresponding to the line 3-3 of Figure 2. Figure 4 is a sectional view, corresponding to the line 44 of Figure 2. Figure 5 is a broken, elevational view of apprtion of the lower exposed end of a shingle. And

Figure 6 is a broken, perspective view illustrating a locking arrangement between two of the shingles.

In said drawing, the shingles are shown as 0 formed of sheet metal arranged in horizontal rows withone row offset a half length of shingle with respect to the next adjacent upper and lower rows. In carrying out the invention, each shingle has a main flat portion or panel 10 provided along its lower horizontal edge with a straight flange 11 of a width corresponding to the desired amount of stepping between the adjacent rows of shingles. Said flange 11 is arranged at right angles to the main panel portion 10, as clearly illustrated in Figure 2, and at one end, the lefthand end as viewed in the drawing, will be outwardly offset as indicated at 111, the thickness of the metal to provide for the overlap joint which occurs as shown best in Figure 4. Along its lefthand side, as viewed in the drawing, each shingle is provided with a flange 12 bent or folded under the main panel portion and slightly spaced therefrom so as to provide a groove or recess for the reception of .a complemental flange 13. Each shingle, along its righthand edge or side will be provided with ,a flange 13, which, as shown, is formed by bending or folding the metal back upon itself on the upper'side thereof, and will be normally spaced 5.1mm the main or panel portion 10 a distance Carlson, Naperville, and Joseph Studer, St. Charles, Ill.

to snugly receive the flange 12 of the next adjacent shingle. As will be apparent from Figure 3, a lock joint is provided along the side edges of each pair of shingles in the same row by sliding the same one toward the right and the other toward the left, relatively.

Along its top edge, each shingle is provided with an approximately semi-circular, upwardly extending flange 14, the concave face of which faces downwardly or toward the lower edge of the shingle, when in position, as shown in Figure 2. Said semi-circular or curved flange 14 will be of such height and extent that the top or free edge thereof will extend forwardly and preferably engage the inner face of the flange 11 of the next higher shingle or shingles at a point approximately three fourths of the height or width of the flange 11. As will be seen from Figure 2, the curved flanges 14, which are underneath the shingles of the next higher row, serve a very important function, in that, any rain, sleet or the like which may be driven under the flanges 11, will be deflected upwardly and thrown back against the inner faces of the flanges 11 and cannot enter beneath the shingles of the next higher rows or become trapped. In other words, a chamber is formed by the curved flanges and straight flanges 11, which serves to automatically destroy the momentum of any rain or other foreign matterthat may be driven upwardly between the shingles and the rain or the like will then drip or drain outwardly from beneath the flanges 11. v

To secure the shingles in place, the righthand edges of each of the shingles, within the folded flange portions and outwardlyof the actual lock joint between two shingles, are provided with circular depressions 1515,which are perforated so as to receive the shanks of nails 16 therethrough, as shown. As will be evident, the nails are entirely covered or protected by the overlapping adjacent shingles, as shown in Figure 3.

As an additional means of locking the shingles together, particularly the lefthand edge of each shingle with respect to the righthand nailed edge of the underlying shingle with which it is interlocked, the following means are provided. Each curved flange 14, near its righthand end, and for a distance equal to or slightly greater than the width of the lock joint, will have a narrow downturned flange 1'? at the free edge thereof and the lefthand end ofv each flange 14 will be slightly out back, ,as indicated at 18, so that its free edge will engage behind the downturned flange 1'7. With this arrangement, when two shingles in the same row are interlocked, as shown best in Figure 3, along their side edges, their top edge curved flanges 14 will also be interlocked for a short distance by the construction indicated at 17 and in Figure 6.

In order to permit of one row of shingles being offset half the width of a shingle with reference to the adjacent rows, and to prevent gaps be tween the flanges l1 and panels of the next lower row of shingles where the lock side joints occur, each flange 11 will preferably be notched at its lower edge at the center thereof, as indicated at 19, for a depth, corresponding to the thickness of the locked joint and the edge of the flange 11 to the right of the notch, as best indicated in Figure 5, will be sloped back toward the 1 right until it becomes alined with the normal straight edge 211 of the flange 11.

In applying the shingles, the same is done from left to right in the same row. A shingle is put in place and is nailed along its right edge, which is then exposed. To accomplish this in an easy manner and to prevent buckling of the shingle, a special block may be employed, corresponding to the slope of the shingle and slope of the roof, which is inserted temporarily under the righthand edge of the shingle so as to support said edge while the nails are being driven home. Such block will be suitably slotted in line with the nail holes so that the nails may be properly driven and the block then Withdrawn. After one shingle is nailed in place, the next shingle in the same row is then slipped over the nailed shingle and moved to the right with respect thereto, until the lock joint is obtained, shown in Figure 3, thus covering the nails of the first applied shingle. The succeeding shingles in the same row are then secured in place in the same manner. After one row of shingles is applied, the next lower row is started. Beginning at the left, the first shingle in the next lower row will have its curved flange 14 hooked under the flange or flanges 11 of the next higher row and the shingle then swung down into its proper position and then nailed. The next shingle in the same row is then applied in a similar manner and interlocked, as will be understood.

With the construction shown, it is evident that the shingles when applied, have the stepped and staggered appearance of ordinary wood shingles. Furthermore, no rain or the like can pass beyond the curved flanges 14, as previously pointed out. The nails are entirely concealed and hence danger of corrosion at the nail holes is eliminated and secure, tight, weather-proof joints are formed along the interlocked side edges of adjacent shingles. The shingles may be easily manufactured; shipped in stacked formation; and no special clips or the like are required so that the same may be applied by the average person without special tools.

Another important advantage of the construction described resides in the particular manner of securing the shingles along their side edges. As clear from inspection of Figure 3, when the nails 16 have been put in place with the side edge of the shingle gauged by the gauge block h'ereinbefore referred to, and the next adjacent shingle overlapped. and interlocked with the nailed shingle, the nail and its head function to not only retain but to support both interlocked edges of the shingles in elevated position with respect to the underlying support. The right hand shingle 10, as viewed in Figure 3, cannot be depressed beyond engagement with the nail head and consequently, because of the interlocked joint with the lefthand shingle 10, the latter cannot be depressed so long as the interlocked joint remains intact. Hence, each shingle is positively supported around all four of its edges and the shingles, when laid, are thereby rendered stiff and rigid notwithstanding that, the shingles may be rather flexible considered individually and when unsecured.

Although there has been shown and described what is now considered the preferred manner of carrying out the invention, the same is by Way of illustration only and all changes and modifications are contemplated that come within the scope of the claims appended hereto.
